PACKING-AUGEFL SPECIFICATION forming part of Letters Patent N o. 707,290, dated August 19, 1902.

Application iiled January Z3, 1902. Serial No. 90,989. (No model.)

T0 all whom it mag/concern.'

Beit known that I, ELMER E. ZIEGENFUSS, a citizen of the United States, residing at Halstead, in the county of Harvey and State of Kansas,have invented certain new and useful Improvements in Packing-Angers; and I do hereby declare the following to be a full, clear, and eXact description ot' the invention such as will enable others skilled in the art to which it appertainsto make and use the same.

The purpose of the present invention is the provision of a packing device of the auger type which will prevent Waste or escape of the commodity being packed when the sack or receptacle is removed from the chute or spout to be substituted by another in the process of sacking, bagging, or barreling flour, meal, bran, grain, and the like.

Packing-angers as generally constructed have an uninterrupted space between the iiights, through which the commodity freely passes,and when replacingafullpackagebyan empty package the commoditybeing packed is liable to and frequently does escape to the floor and is either wasted or becomes mixed with foreign matter, which renders it unfit for domestic use in the preparation of food.

This invention combines with a packingauger an automatically-closing gate which opens under pressure of the commodity to provide a passage thereof to the package when the commodity is being forced into the bag or other receptacle and which closes the instant the packing pressureis released, so as to prevent escape of the iiour or other commodity being packed.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result reference is to be had to the following description and drawings hereto attached.

While the essential and characteristic features of the invention are susceptible of modification, still the preferred embodiment of the invention is illustrated in the accompanying drawings, in which- Figure 1 is a perspective view of a packingauger embodying thev invention as seen from zontal position. Fig. 4 is a detail section showing the mountings and connections for the gates. Fig. 5 is a detail sectionr on the line X X of Fig. 4, showing the parts on a larger scale. Fig. 6 is a detail perspective View of a portion of a gate, showing the pintle-rod to which it is lattached and the spring and packing coperating therewith.

Corresponding and like parts are referred to in the following description and indicatedA in all the views of the drawings by the same reference characters.

The head of the packing-auger comprises a stem l and flights 2, either formed with or attached to the saidstem. Gates 3 close the spaces formed between the separated ends of the iiights and are preferably hinged to the upper or front ends of the nights and to close against the rear ends of theother flights. The precise manner of mounting `the gates is unimportant within the purview of the invention so long as they'serve to close the spaces between the proximal ends of thenilights and prevent escape of the commodity when the device is relieved from packing pressure. It is preferred to hinge the gates to the upper or front ends of the flights, so as to take advantage ofthe weight of the commodity to assist inautomatically opening the gates when the auger is rotated or relieved from packing pressure. When thev auger is rotated and flour or other commodityis supported by the iights, the gates 3 are crowded against the commodity and are opened, thereby permittingfree passage ofthe material or breadstuff to the sack or other receptacle into which the flour or meal is to be packed. When the operation ceases for an instant, due to substituting Van empty package for the one tilled, the gates automatically close, thereby preventing escape of the commodity, the same be proportioned according to the work to be performed and resistance to be overcome. As shown, a pintle-rod 4c pivotally connects eachpf the gates with the flight and is connected with the gate in any substantial way, so as to turn therewith. One end of a spring 5 is connected with the pintle-rod, and its other end has connection with the packinghead, and the spring is so arranged as to effect a closing of the gate when the auger is not in packing operation. The spring 5 is of the spiral type and is located in a barrel 6, provided at a side of the stem l, the inner end of the pintle-rod entering said barrel. A packing-Washer 7 is fitted to the inner end portion of the pintle rod and comes close against the outer side of the barrel, so as to close the opening therein through which the pintle-rod passes, and thereby exclude all dust from the barrel and spring. A cap 8 is fitted to the barrel and forms a space in which the packing-washer 7 is located and assists, further, in preventing entrance of dust into the barrel.

Having thus described the invention, what is claimed as new isl. In a packing-auger, a gate for closing the space between the iiights hinged to the flight above said space and adapted to swing under said flight when the auger is in operation, substantially as set forth.

2. In a packing-auger, an automaticallyn closing gate for the space between proximal ends of the flights, said gate being hinged to the upper end and adapted to close against the lower end of the said flights, substantially as set forth.

3. In a packing-auger, a gate for closing the space between the proximal ends of the flights, a pintle-rod having connection with the gate, a barrel applied to the stern of the auger, and a spiral spring located in said barrel and having one end connected thereto and its opposite end connected with the pintle-rod, substantially as specified.

4. In a packing-auger, a gate for closing the space between proximal ends of the flights, a barrel applied to the stem of the auger, a spiral spring located Within the barrel having its outer end connected thereto, a pintlerod having the gate connected therewith and having its inner end fitted into the barrel and connected to the inner end of the spiral spring, a packing-washer secured to the inner end portion oi the pintle-rod, and a cap cooperating with the said barrel to inclose the said washer, substantially as set forth.

In testimony whereof I aix my signature in presence of two Witnesses.
